To all whom it may concern:

Be it known that I, Ennns'r MILTNER, a citizen of the United States, and a resident of Newark, in the county of Essex and have invented certain new and useful Improvements in Apparatus for the Manufacture of Celluloid andles, of which the following is a specification.

lhe invention relates to improvements in apparatus for the manufacture of celluloid handles and the like, and it consists in the novel features and combinations of parts hereinafter described and particularly pointed out in the claims. 7

I present herein the apparatus of my invention as desi ed for the manufacture of hollow cellulold handles or handle-shells hes. In this manufacture, I place a celluloid tube closed at one end in a die and soften after which I expand the tube against the walls of the matrix of the die by means of air under pressure delivered into the open end of the tube, and thereafter cool the hollow handle-shell thus formed by the use of water or the like. The method of manufacturing the handle-shells is described and claimed vin an agplication filed May 21, 1910, for Letters atent for the same, and the present invention resides in a suitable apparatus or machine adapted for use in carrying out said method and in manufacturing the handle-shells in an etiicient and economical manner and in considerable number at each operation of the machine.

- The machine of my invention comprises a press having upper and lower sections adaptedto receive heating and cooling circulating agents (steam and water) as the same may be requi ed,'a die or dies having a plurality of matrices between said sections to receive the celluloid tube-sections from which the handle-shells are to be formed, a series of nozzles for the delivery of air under pressure into the tube-sections, means for supplying said nozzles with the air, and means for efi'ecting the simultaneous movement of the nozzles toward and from the dies.

The invention will be fully understood from the detailed description hereinafter the same therein by heat,

'15 a slide connected presented, reference being] had to the accompanying drawings, in which:

Figure 1 is a side view of a machine embodying my invention; Fig. 2 is a front view, partly in vertical longitudinal section, of the same; Fig. 3 is a vertical section of the same on the dotted line 3-3 of Fig. 2; Fig. 4 is an enlarged detached section corresponding substantially with that of Fig. 3, of the means at one end of the press carrying the series of nozzles for delivering air under pressure to the tube-sections held within the matrices of the die; Fig. 5 is a top view, partly in section, of the same; Fig. 6 is a detached top view on a reduc scale and partly broken away, of one of the dies having a series of matrices at each side for the formation of the handle-shells, a part of the top section (if the die being removed, and Fig. 7 is a vertical transverse section on a larger scale of the In the drawings, 10 of the ress, 11 the vertically movable platen thereo ,-12 guide rods for said platen, 13 the transverseoperating shaft having an eccentric 14 for raising and lowering the platen, with the platen by a screw 16 and with the eccentric 14 by an eccentric rod 17 and 18 a suitable frame secured upon the u per ends of the bolts or rods 12 and afio in at.'ts central portion a guide-way 19 for t e slide 15. The frame 18 supports suitable bearings 20 for the shaft 13 which is provided on one end with an arm' 21 carrying a weight 22 and on its other end with a frame 23 to which suit-- able operating handles 24 are secured, said handles being used by the operator for turning the shaft 13 in one direction or the other and thereby elevating or lowering the platen 11 in a direction from or toward the. base 10. The shaft 13 is provided with an adjustable stop 25 to prevent its movement to an undue extent in either direction, said stop being adapted at one end to rest frame 18 when the platen 11 is in its lower position and at its other end to engage said frame when the platen is in its elevated position.

The slide 15 is same.

in the form of an open end of the screw 16 and provided with designates the bed;

on the bearing apertures, 26 for the ends of the shaft 27 carried by the lowerend or the eccentric rod 17. The slide 15 snugly fits without binding against the guideway 19, which is a vertical opening of appropriate form in the center of the frame 18. The screw 16 enables an ad'ustment of the platen 11 and slide 15 in t eir relation .to each other. Upon the bed plate 10 is secured a cored plate or frame 28 having a serpentine channel 29 extending through it and equipped at one end with an inlet pipe 30 and at its other end with an outlet pipe 31. The plate 28 is formed at its slde ed es with upwardly extending flanges 32, t e presence of which creates a broad the plate adapted to receive the ower section 33 of the die or dies utilized on the machine, said section fitting between the flanges 32 and being locked 111 position by means of screws 34 extending through said flanges. Upon the lower side of the platen 11 is secured a plate 35 corresponding exactly with the plate 28 and having the serpentine channel 36 through it equipped at one end with an inlet pipe 37 andat its other end with an outlet pipe 38. The plate 35 has at its side edges flanges 39 corresponding with the flanges 32 of the plate 28 forming a broad groove to receive the upper section .40 of the die or dies which may be used on the press, said upper section of the die or dies being secured in osition between the flanges 39 by means 0 screws 41. When, I desire to heat the dies formed of the lower and upper sections 33,40 I cause steam to flow throu nels 29, 36 in the p ates 28, 35, and at the proper time when it is desired to cool the dies and the handle shells therein, I cease the feed of steam to said channels and cause water to flow throu h the same, the water serving to cool the p ates 28, 35 and the die sections.

In. the drawings I illustrate two dies arranged between the .lower and upper plate sections 28, 35, and each of these dies er- .tends the full width of the platen 11 and contains a series of matrices 42 conformin to the shape of the handles to be produce it bein my pur ose to malre at each operation 0 the machine a considerable number of handles. As a matter of convenience in the manufacture of the dies l provide each die with two sets of matrices 42 arranged end to end, as shown in Figs. 3, 6 and 7, but will only use the outer row of said matrices of each die. The dies are reversible so that either row of matrices therein may become the outer row, and it will frequently be the case that one row of the matrices of a'die will (litter in outline itroinv another row Oil said matrims, and under such circumstances the die will he so placed on the nozzles 44 by which the air, is delivered to the celluloid I placed within said matrices. oove in i *within said tube of the nozzles will enter said nozzl jFig. 4. After'the lower section 33 h the serpentine chan-v softeningA nuances ently'to'be described. I do not confine the invention to the employment of two rows of" matrices in each die, but in my practice refer to so construct and use thedies. en the dies are on the press their outer edges are exposed at the front'and rear ends of the press sections 28, 35, as shown in Figs. 3 and 4, said dies at their exposed edges having recesses 43 extending from the matrices 42 thereof and exposed to receive the air under pressure, tube sections 45 The platen 11- of the press is elevated so as to 'separate the upper section of the die or dies ruin the lower section thereof when it is desired to place the celluloid tube sections 45 in the matrices of the dies, and in placing said tube sections in the dies the open outer end of the tubesections'should be placed 'withinthe exposed recesses 43 of the diesso that when the. air nozzles 44 are in position to deliver air under pressure sections, the tapered ends the open ends of the tubes and force the material thereof outwardly against the walls of the recesses. 43, thereby forming air-tight joints between es and tubes as representedin celluloid tube sections placed within the matrices of the of the dies the platen ll of the ress will be lowered to match the upper ie section 40 upon the lower section have been 33 and effect the requisite pressure for maintamingthe die sections in proper relation to each other. Steam may. thereupon be ad? mitted through the sections 28, 35 for the celluloid tube sections held Within t e dies. After the celluloid tube sections have become sutiiciently softened by heat, air' under pressure is delivered from nozzles 44 into said tube sections for the purpose of expanding them outwardly against the walls of the matrices 42 and converting them from the condition cl a tubular blanlr closed at one end to a coml integral handle shell of the shape dfill by the matrices oil the dies, the she e shbwn one intended for handles ol shaving brusles. hitter the celluloid tube sections have been expanded by the air under pres sure into the handle shells, ll cool the dies and said shells by causing water, in lieu olf the steam previously employed, to circulate through the channels 29, 3% or the plate sections 28, 35, this cooling or the plate sections resulting in the dies and the handle shells being cooled and in said shells lasing set, so thereafter they will inst warp or materially hrinlr.

nozzles 44 into the cellulo' manipulating air underpressureto be delivered to the tube sections within the dies-,- 1s shown more clearly in Figs. 1, 3, 4 and- 5, said means being duplicated at the front and back of the machine, so that one set of the mechanism may be utilized in connection with the die whose recesses 43 are exp at the front of the machine and the other set "employed in connection with the other die whose recesses 43 are exposed ,at the Each set of the mechanism provided for the air comprises base frames 46, an elongated cylindrical casing 47 having aforwardly extending web- 48 supporting an inte al head 49 which receives the shank en of the series of nozzles 44, said head being formed with an undercut groove to receive the shank ends of the nozzles, which are in individual parts and connected together by a bolt 50. The cylindrical casing 47, web 48, and head 49 are greferably integral with each other and with ove-tail bars 51 disposed adjacent to each end of the cylindrica ed to have a sliding or reciprocating movement within dove-tail recesses 52 formed in the base frames 46. The cylindrical casing 47 is supplied with the air under pressure through a pipe 53, and said casing by means of a series of pipes 54 is connected with i the individual nozzles 44, which have outlet passages 55 throudgsh them and are adapted at their outer en to enter the celluloid tubes 45 held within the dies. The cylindrical casing 47 and head 49 are adapted to have a reciprocating movement toward from the dies and will be actuated by means of an operati shaft 56 mounted in the outer ends of t and having thereon eccentrics 57 connected by straps 58 and rods 59 with studs 60 rojectin from the ends of the casin 47. he she t 56 is a rock shaft andwil be pi'ovided with handles or levers 61 for enabling the attendant to conveniently rock the shaft and thereby through the eccentrics and other connections cause the cylindrical casing 47 and its connected parts to have a reciprocating movement toward and from the dies for the purpose of rojecting the 1d tubes when required and withdraw said nozzles from said tubes at the required period.

The invention will be understood from the foregoing description without further extended explanation. The platen 11 is elevated to expose the matrices of the dies and the celluloid tubes are inserted in the outer rows of said matrices, and thereu on the platen is lowered to close the dies. team is circulated through the plate sections 28, 35 to heat the dies and soften the celluloid tube sections inclosed therein. After the celluloid tube sections have become suficiently softened, the handles 61 are operated to move casing 47 and adaptand e side arms or frames 46' the series of nozzles '44'toward the dies until the tapered ends of said nozzles enter the open ends of the celluloid tubes and press the material thereof outwardly against the walls of the recesses 43" in the dies, and

thereupon air under pressure is admitted through the pipe 53 to the cylindrical casing 47, whence. it will pass through the pipes 54 to the series of nozzles 44 and thence enter the celluloid tubes and expand the same against the inner walls of the dies, thus transforming said tubes into the appropriate outlines for handles? After the handles have been formed the attendant may cut off the air from the'casin 47 and nozzles 44 and'by means of the hand es or levers 61 retract the nozzles from the dies. The handles will be cooled while'within the dies by the circulation of water through the plate-sections 28, 35. After the operation has been completed,

, the platen 11 will be elevated and the hollow handles or handle shells removed from the dies, and thereupon an additional supply of the celluloid tubes will be laced in the dies and the operation repeated? At each operation of the machine a considerable number of the handle-shells are produced, the number depending on the number of matrices in the dies.

I have employedthe term. celluloid? in the foregoing material used by me in manufacturing-the handles. Celluloid is a pyroxylin material and the same material is well-known by other commercial names. My'invention is not limited therefore rial technically-called celluloid, and I use the word celluloid. in this application as denoting broadly pyroxylin material of the general character of commercial'celluloid, or any material of the plastic class capable of .use in utilizing my inventlon.
